In an electric field $E=20rsin{a}_r+10rcos{a}_{}\frac{V}{m},$ calculate the energy expended in transferring a $10-nC$ charge

$($a$)$ From $A(5,30,0)$ to $B(5,90,0)$

$($b$)$ From $A$ to $C(10,30,0)$

$($c$)$ From $A$ to $D(5,30,60)$

$($d$)$ From $A$ to $E(10,90,60)$

Can you please show all work and explain it step by step
